Really?
I was reponding to references about using the "same pump" in a 10
gallon brew and a 50 gallon brew. The "just a guess" was only in
relation to the specific example. Every pump is different as a simple
search of the internet will tell you.
My point was that just tossing around pump capacities at atmospheric
pressures if far "less than useful"
You may know about back pressure and pump ratings, but the posts so
far that list a X cfm pump sure don't seem to take that into account.
Are you saying that I am wrong that there is a huge difference between
a roots type blower and a squirrel cage blower rated at the same
volume, when you then drop the output tube 4 feet under water?
If I am wrong about that, then please explain how. If I am right, then
explain how my pointing it out makes my post less useful than your's
when you do not point it out?
